Owl

Information

The purpose of the Owl plug-in is to constitute a new data type named Tensor, thanks to which the Grasshopper users will be able to work with so-called "big-data". This will further open up new possibilities to use more sophisticated machine-learning tools, which require big data sets to be effective.

The core library of the Owl plug-in is open sourced, and provides the developers with methods to read/write and use the Tensor data within the GH (and outside of it).

Additionally the Owl.Accord.GH.gha plug-in is the first extension based on the Owl core, utilizing few of the machine-learning methods sourced from the Accord framework.

Comment by Radul Shishkov on March 26, 2019 at 2:11am: Hi everyone ,

I have a problem with the "compute" component: after doing one computation it seems to get stuck and the output wouldn't change after changing the input tensor. It seems like the calculation of any network doesn't work properly. I have this problem on two different computers , using Rhino 5 and Owl 1.0. Anyone with same problem or idea that am I doing wrong ? Thanks in advance !

Comment by Ángel Linares on August 7, 2017 at 2:01am: Hi Ortler,

Yes, that is what I meant by using scripting. But I just wanted to know if was there any built-in component doing the work ;)..it looks like there is no :P

Thanks for the reply.

Comment by Ortler Mark on August 7, 2017 at 1:53am: @Ángel Linares...
you could split the tensor in its nummeric parts and then use the same method as for euclidean vectors to calculate the distance:
sqrt(a²+b²+c²+d²+e²+...) u see? simple pythagoras...

If u need more operations like "dotproduct" or "crossproduct" for tensors let me know...

greets

Comment by Ángel Linares on August 7, 2017 at 1:41am: Hi all,

Has anyone try to calculate the distance between several tensors in nD? As far as I can see there is no component for that straight away. If scripting is the only way I will go that way, but just wanted to check first in here.

Thanks in advance.
